{"id":"CVE-2026-89148","state":"PUBLISHED","title":"AVideo Open Redirect via playlistSort.php Referer Header","description":"AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains an open redirect in objects/playlistSort.php. Because the endpoint is not a *.json.php script, AVideo's automatic CSRF guard (autoCSRFGuard()/forbidIfIsUntrustedRequest()) does not run, and when the request includes the sort parameter the script issues a Location header set to the unvalidated $_SERVER['HTTP_REFERER'] value without calling isSafeRedirectURL(). A remote unauthenticated attacker can therefore induce a logged-in user who can manage the targeted playlist to submit a cross-origin POST with a crafted Referer, causing the victim's playlist to be reordered and the victim's browser to be redirected from a trusted AVideo URL to an attacker-controlled site for phishing. No patched version is available.","publishedAt":"2026-09-11T11:15:20.243Z","updatedAt":"2026-09-11T12:50:13.116Z","severity":{"score":5.1,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N","source":"VulnCheck"},"assigner":"VulnCheck","products":["WWBN AVideo"],"affected":[{"vendor":"WWBN","product":"AVideo","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"c3edcc274c389816d434acadac07ee78eaf330c1","versionType":"git"}]}],"references":["https://github.com/WWBN/AVideo/security/advisories/GHSA-jj4v-c999-cm2m","https://www.vulncheck.com/advisories/avideo-open-redirect-via-playlistsort-php-referer-header"],"weaknesses":["CWE-352"],"ingestedAt":"2026-10-29T20:13:26.108Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/89xxx/CVE-2026-89148.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-89148","state":"PUBLISHED","datePublished":"2026-09-11T11:15:20.243Z","dateUpdated":"2026-09-11T12:50:13.116Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-09-11T01:23:39.045Z"},"containers":{"cna":{"title":"AVideo Open Redirect via playlistSort.php Referer Header","descriptions":[{"lang":"en","value":"AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains an open redirect in objects/playlistSort.php.
